[0045] Furthermore, guide grooves 12 are evenly arranged at positions corresponding to guide grooves 11 on the protection box 10, and one end of the driving shaft 24 corresponding to the protection box 10 is rotatably connected to a pull ring 70, and limit blocks 71 are evenly fixed on the pull ring 70, and the limit blocks 71 are located in the guide grooves 12. A plurality of limit blocks 71 are located in the corresponding guide grooves 12, so that the pull ring 70 is restricted, so that the pull ring 70 can only move along the guide grooves 12, thereby driving the cutting blade 23 to move, so that the cutting blade 23 moves to cut the steel pipe.

[0046] Furthermore, the guide ring 50 is in a circular ring shape, the guide groove 1 11 and the guide groove 2 12 are both arc-shaped, and the centers of the guide ring 50, the guide groove 1 11 and the guide groove 2 12 coincide with the rotation center of the shaft 22; this ensures that the cutting blade 23 is not obstructed when rotating around the shaft 22.

[0047] Furthermore, the other end of the drive shaft 24 is connected to the motor 40 through a transmission assembly, which may be a transmission belt. The projection of the rotation center of the motor 40 on the protective box 10 coincides with the rotation center of the rotating shaft 22; this ensures that the cutting blade 23 can be driven by the motor 40 while rotating around the rotating shaft 22, thereby performing cutting work.

[0048] Furthermore, a through hole 16 is opened through the protective box 10, and the steel pipe is cut by the cutting blade 23 after passing through the through hole 16. Platforms 30 are symmetrically fixed at positions corresponding to the through holes 16 on both sides of the protective box 10. The platform 30 can ensure that the steel pipe remains in a horizontal state after passing through the through hole 16, and the motor 40 is installed on the platform 30.

A driving member 63 can be rotatably installed on both sides of the protective box 10. The driving member 63 includes a U-shaped pressure plate 631 and two tilting rods 632. The pressure plate 631 is against the elastic member 62, and the other end of the tilting rod 632 is fixed with a clamping plate 64, and the clamping plate 64 is located on the corresponding side. in the through hole 16; when in use, the pressing plate 631 is pressed downward so that the tilting rod 632 drives the clamping plate 64 to move upward, and the steel pipe is passed through the through hole 16, and then the pressing plate 631 is released. Due to the rebound ability of the elastic member 62, the tilting rod 632 drives the clamping plate 64 to clamp on the surface of the steel pipe, so that the steel pipe is fixed, which effectively prevents the steel pipe from tilting at both ends during the cutting process and causing an uneven cutting edge, and at the same time effectively prevents the steel pipe from tilting at both ends during the cutting process and popping out to cause a safety hazard.

[0051] like Figure 2 As shown;

[0052] A slope 13 is provided at the bottom of the inner cavity of the protective box 10, and a discharge port 14 is provided on the protective box 10 at the inclined end of the slope 13 corresponding to the protective box 10; when cutting, a large amount of sparks and impurities will be generated, which will fall to the bottom of the inner cavity of the protective box 10, slide down along the slope 13, and finally be discharged through the discharge port 14 for easy cleaning.

[0053] The working principle of the utility model is as follows: when in use, first press the pressure plate 631 downward so that the tilting rod 632 drives the clamping plate 64 to move upward. At this time, the steel pipe is passed through the through hole 16, and then the pressure plate 631 is released. Due to the resilience of the elastic member 62, the tilting rod 632 drives the clamping plate 64 to clamp on the surface of the steel pipe, so that the steel pipe is fixed. Then start the motor 40 to rotate the cutting blade 23. Finally, move the pull ring 70 on the guide groove 12 to rotate the cutting blade 23 around the rotating shaft 22. When the cutting blade 23 rotates to the through hole 16, the cutting blade 23 will cut the steel pipe until it is cut into two sections. During the entire cutting process, the cutting blade and the cutting point of the steel pipe are located in the protective box 10. The protective box 10 provides all-round shielding to improve safety.
